The gas is Cl2 and the halate used in fire works and safety matches is$\mathrm{K}\mathrm{C}\mathrm{l}{\mathrm{O}}_3$
$\underset{\begin{array}{l}\mathrm{g}\mathrm{r}\mathrm{e}\mathrm{e}\mathrm{n}\mathrm{i}\mathrm{s}\mathrm{h}\\ \mathrm{y}\mathrm{e}\mathrm{l}\mathrm{l}\mathrm{o}\mathrm{w}\mathrm{g}\mathrm{a}\mathrm{s}\end{array}}{3\mathrm{C}{\mathrm{l}}_2}+6\mathrm{K}\mathrm{O}\mathrm{H}\to \underset{\begin{array}{l}\mathrm{p}\mathrm{o}\mathrm{t}.\mathrm{c}\mathrm{h}\mathrm{l}\mathrm{o}\mathrm{r}\mathrm{a}\mathrm{t}\mathrm{e}\\ \left(\mathrm{H}\mathrm{a}\mathrm{l}\mathrm{a}\mathrm{t}\mathrm{e}\right)\end{array}}{\mathrm{K}\mathrm{C}\mathrm{l}{\mathrm{O}}_3}+5\mathrm{K}\mathrm{C}\mathrm{l}+3{\mathrm{H}}_2\mathrm{O}$
As bromine is reddish liquid and${\mathrm{I}}_2$is violet solid so they are ignored here.
